If your trading Indicies.. Nadex intra day is the best..
Options are so bad I am telling you.. you only get 1:1 on an option if you buy same day on a 20 pt move on SPX Nadex you will get at least 2.5:1..
Same with Nasdaq probably 3:1 on a 100pt move but 1:1 on an option same day..
Intraday doesn't cut it. I need the next day option on the day prior.
The thing is that I trade a systematic quant model, and the chosen expiration day is fixed at +1 day, or +4 days or +6 days. That means if a signal is trigged on monday, I need the tuesday expiration on monday 5 minutes before option market closing. Today if the expiration is out of sync I have to sometimes buy a one day longer expiration and manually close it on the day I need to to close instead of leaving it to go to OCC clearing. It's suboptimal for me.
